SportsTracker is an application for recording sporting activities. It is not bound to a specific kind of sport, as categories can be created for all sport types, such as cycling, running, or tennis. The main advantages are the good overview of your exercises and the easy creation of exercise statistics for specific time ranges and sport types. Users of heart rate monitors (Polar and CicloSport) can import, display (including diagrams), and organize the recorded exercise data.

With MetaModel, you use a type-safe SQL-like API for querying any datastore. It is a data access framework providing a common interface for exploration and querying of different types of datastores. It isn't a data mapping framework. Instead, it emphasizes abstraction of metadata and the ability to add data sources at runtime, making MetaModel great for generic data processing applications, but less so for applications modeled around a particular domain.

dlg2html is a set of Bash shell scripts which help automate the
conversion of DLG Pro message bases to HTML for archiving or mirroring
on the Web. (DLG Pro is a Bulletin Board System for Amiga personal
computers.) The HTML message files contain the appropriate links to the
next and previous messages, as well as to any replies or referenced
messages. A message index is also produced. dlg2html works with terminal
dumps of DLG message boards, which means that you do not need access to
the actual BBS files to perform the conversion.
